A business with 5 copy machines keeps track of how many copy machines need service on a given day.It believes this is binomially distributed with a probability of p = 0.2 of each machine needing service on any given day.It has collected the following based on a random sample of 100 days.
Given this information,assuming that all expected values are sufficiently large to use the classes as shown above,the critical value for testing the hypothesis will be based on 5 degrees of freedom.

Quizplus · Accepted Answer

The statement about the critical value for testing the hypothesis based on 5 degrees of freedom is irrelevant and misleading in the context of the given information. The question doesn't provide enough information to perform a hypothesis test or calculate critical values based on degrees of freedom. Therefore, the answer is B, as the statement is false.
